AYF534035 FFC/FPC Connector - Equivalent & Substitute Parts

Part Overview

The AYF534035 is a 40-position FFC/FPC connector manufactured by Panasonic Electric Works, designed for surface mount, right-angle applications with 0.5mm pitch contacts. This connector features flip lock and backlock locking mechanisms, gold-plated copper alloy contacts, and LCP housing material rated for 50V operation across -55°C to 85°C temperature range.

The AYF534035 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AYF534035 are identified based on the following critical parameters that determine functional compatibility:

• 40-position connector configuration with 0.5mm pitch spacing
• Surface mount, right-angle orientation for PCB integration
• Top and bottom contact arrangement for dual-sided signal routing
• Flip lock and backlock locking mechanisms for secure mating
• Gold-plated copper alloy contacts for reliable electrical connection
• UL94 V-0 flammability rating for safety compliance
• RoHS compliance for environmental and regulatory adherence

The substitute parts AYF564035A and FFC2B28-40-G meet these core functional requirements. Variations in height above board, current rating per contact, voltage rating, and operating temperature range represent acceptable parameter differences within the FFC/FPC connector category, provided the application requirements do not exceed the substitute part specifications.

Parameter Comparison

Engineering Selection Recommendations

AYF564035A (Panasonic Electric Works): This substitute maintains Panasonic Electric Works manufacturing continuity and preserves the LCP housing material and full -55°C to 85°C operating temperature range of the original AYF534035. The primary difference is increased height above board (1.80mm versus 1.00mm) and reduced current rating per contact (0.4A versus 0.5A). This part is active and RoHS compliant. Selection is appropriate for applications where the increased height does not create mechanical constraints and current requirements do not exceed 0.4A per contact.

FFC2B28-40-G (GCT): This substitute provides the same height above board (1.00mm) and maintains all core connector specifications including 40-position, 0.5mm pitch, right-angle surface mount configuration. The GCT part features thermoplastic housing material, reduced voltage rating (30V versus 50V), reduced current rating (0.2A versus 0.5A per contact), and narrower operating temperature range (-25°C to 85°C versus -55°C to 85°C). This part is active and ROHS3 compliant. Selection is appropriate for applications operating within 30V maximum voltage, 0.2A maximum current per contact, and -25°C to 85°C temperature range.

Both substitute parts are active products with current availability and full RoHS compliance, addressing the obsolescence status of the original AYF534035.

Frequently Asked Questions (FAQ)

Q: Can AYF564035A be used as a direct replacement for AYF534035?

A: AYF564035A is functionally compatible for 40-position, 0.5mm pitch FFC/FPC connector applications. The increased height above board (1.80mm) requires verification that PCB layout and mechanical clearances accommodate this dimension. Current rating reduction to 0.4A per contact must be confirmed against application requirements.

Q: What are the key differences between AYF534035 and FFC2B28-40-G?

A: Both connectors share identical 40-position, 0.5mm pitch, right-angle surface mount configuration and 1.00mm height above board. FFC2B28-40-G differs in voltage rating (30V maximum), current rating (0.2A maximum), operating temperature range (-25°C to 85°C), and housing material (thermoplastic versus LCP). These differences require application-level verification.

Q: Is the FFC2B28-40-G suitable for high-current applications?

A: No. FFC2B28-40-G is rated for 0.2A maximum current per contact, significantly lower than the original AYF534035 (0.5A per contact). Applications requiring current levels above 0.2A per contact must use AYF564035A or identify alternative connector solutions.

Q: What is the impact of housing material differences between these connectors?

A: AYF534035 and AYF564035A use Liquid Crystal Polymer (LCP) housing, while FFC2B28-40-G uses thermoplastic housing. Both materials meet UL94 V-0 flammability requirements. LCP provides superior thermal stability and dimensional consistency across the full -55°C to 85°C temperature range. Thermoplastic housing in FFC2B28-40-G is rated only to -25°C minimum.

Q: Are all three connectors RoHS compliant?

A: Yes. AYF534035 and AYF564035A are RoHS compliant. FFC2B28-40-G is ROHS3 compliant. All three meet environmental and regulatory compliance requirements for RoHS-restricted substance limitations.

Q: What packaging formats are available for these substitute parts?

A: AYF534035 is supplied in Cut Tape (CT) and Digi-Reel packaging. AYF564035A is supplied in Strip packaging. FFC2B28-40-G is supplied in Cut Tape (CT) and Digi-Reel packaging. Packaging format selection depends on production volume and assembly process requirements.
